Abstract

PURPOSE: An aminosulfonate salt is made to act on an epoxy resin bearing terminal epoxy groups to produce the titled resin having specific water-soluble terminal groups and showing high water resistance through simple processes.
CONSTITUTION: An aminosulfonate salt of formula II (R3 is H, 1W20C alkyl; R4 is 1W6C alkylene, substituted alkylene; M is amine, alkali metal, ammonia) such as taurine is made to act on an epoxy resin having terminal groups of formula I (R1, R2 are H, methyl) and the reaction product is treated with an acid such as hydrochloric acid to produce the objective resin having terminal groups partially modified to the groups of formula III. The resultant resin only or a mixture thereof with an aminoplasto resin is dissolved or dispersed in a basic medium to give a water- based epoxy resin or adhesive.
